This is my very first time running across one of these in person and I searched. This is plug and ploy and can be found through the site if you use the search function. 97 is the only year where this handy dandy upgrade drops right in. Not even the 94-95 scs get an 8k tach so yeah for 97s only. I understand these are hard to come by most of the time. I find the old shos all the time but this wasn't even a SHO just a bird where someone had this swapped in.
